CHINE roaroRMING HEEL-CALKS on HoRsEsHoEs.

. Application filed February 23, 1912. Serial No. 679,448.

To all whom it may concern: l

Be it known that I, JAMEsNVooD, a citizen of the United States and aresident of Noblesville, county of Hamilton, and State of Indiana, haveinvented a certain useful Machine for Forming HeeLCalks on Horseshoes;and I do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawings.

The object of thisinvention is to facilitate the formingof heel calks ofhorse shoes and consists essentiallyof means for simultaneously bendingand shaping the calk and shearingaway the surplus metal necessary to theshaping. This means includes a die having a suitable recesswhich issubstantially the shape of the Call: in vertical longitudinal sectionand a jaw or bar movable withreference to the die uponfithe end of thehorse shoeso' as tobend it down into the i die and shear away thesurplus metal.

The shape of the calk is determined by the shape of the recess in thedie and it'may be triangular or substantially rectangular, as desired. aI Along with the foregoing there is means for holding the horse shoe inplace above the die while it is being sheared.

The device is a very simple one in both construction and operation;

The nature of the invention willcbe unand the following description andclaims:

In the drawings, Figure 1 is a side ele-- vation of the machine with theparts in idle position. Fig. 2 shows the same, but with a horse shoeheld in position and with the parts of the machine shown in operatedposition. Fig. 3 is across section through the dies of Fig. 2, showing aheel calk being formed. Fig. 4 shows the same, but with a modified formof die being used.

In detail there is shown in the drawings a horse shoe heel calk formingmachine having a vertical frame bar 10 with a horizontal frame 11secured upon the upper ends and with a pedaloperated clamp 12 and alever operated forming, bending and shearing jaw or bar 13 by means ofwhich a horse shoe may be held and heel ca'lks formed thereon andsheared to any desired shape. -The vertical frame bars 10 are supportedby means of legs 14, although any other means would suffice. I Thehorizontal frame 11 is substantially inginwardly over the die 15. footpedal 23 pivoted at 24: upon the lower the dies 15, see dotted lines inFigs. 1 and 2, are secured by means of a bolt 16. Said Patented Mar. 4,19,13.

dies have suitable depressions or cut away portions 17 upon theleft-hand face and spacedapart a distance equal to the dis tancebet-ween the heels upon the horse shoe upon which itis desired to formheelcalks.

of. the horizontal frame '11 and upon said barandinf the opening of theU, the clamping bar 12 is pivotallymounted and within the clamping bar,the'shearing bar-13 is A pivoted bar18 extends through the legs mounted.At the extreme left h'and'end of the frame 11 a bell crank lever 19'ispivoted by means of a pin 20. The clamping bar 12 is also somewhatU-shap'edin form and'Jas before mentioned, is pivoted upon the pin 18.The sides o-f said bar lie in a vertical plane and the end 21 normallylies in a horizontal plane such that when said bar is moved totheposition shown in Fig.

2, the end'21 will bear against the horse shoe.

22 and hold the same against the horizontal frame 11 with the heels ofsaid shoe project- There is a end of the vertical frame 10 and pivotallyconnected to the clamping bar 12 by means" of rods 25, one upon eitherside of the .framell. There ,is a spring 26 securedto a said frame andto the foot pedal 23 by -means of which said foot pedal and'saidclamping bar are returned to their normal positions when said foot pedalis released.

The heel forming and shearing bar 13 mounted within the clamping bar 12upon the pin 18 has its right-hand end formed concentrically with saidpin and is hardened to form a cutting edge 27 thereon. There is adownward projection 28 upon the lower side of said shear which ispivotally connected with one end of a link 29,

whose other end is pivoted to one end of a lever 30 which is fulcrumedbetween its ends on a pivot 31 extending through the bars 10 and withthe other endpivoted to one end of a link 32 whichis also pivoted in thefree end 33 of the bell. crank lever 19.

The operation of the machine is as folthe position shown in Fig. 1toward that shown in Fig. 2. This, through the connect-- ing link 32,lever 30 and link 29, will cause the cutting edge 27 of the shear 13 tobear against the inwardly projecting heels of the horse shoe 22 and willbend them downward, filling the depressions within the dies 15 andshearing away the surplus metal, thus, at one operation, forming,shearing and finishing the calks 33 upon said horse shoe 22. The lever19 is then thrown back to the normal position, shown in Fig. 1, and theclamp 12 is released by removing the foot from the pedal 23 and thefinished horse shoe may be removed from the machine.

In Fig. 4 a modified form of die 34 is shown as substituted in place ofthe die 15 for the purpose of forming a calk with a blunt instead ofpointed end. The particular form of die, however, constitutes noessential part of the invention as many different shapes may be usedwith equal facility, provided that the upward face of the die isconcentric with and has the same radius as has the cutting edge 27 ofthe shear 13.

I claim as my invention:

1. A machine for forming heel calks for horse shoes including a mainframe, a vertically disposed die removably secured within the end ofsaid frame upon which the horse shoe is adapted to be placed, a yokeframe pivoted to the rear part of the main frame with the forward end ofthe yoke frame adapted to move down upon the free end of the main framefor holding the horse shoe 111 place, a pedal bar, a rod connecting thepedal bar with said shoe holding bar, a spring connecting the pedal withthe main frame so as to hold the shoe holding bar normally elevated, ajaw-like bar fulcrumed in the rear part of the main frame with theforward end vertically movable adjacent the rear surface of the die, anactuating lever, and a connection between said actuating lever andjaw-like bar for oscillating the latter.

2. A machine for forming calks on horse shoes including a main frame, asupporting frame, a vertically disposed die removably secured withinsaid main frame upon which the horse shoe is adapted to be placed, aclamping frame fulcrumed upon said main frame with the forward endthereof adapted to move down upon said main frame for holding the horseshoe in place, a foot lever fulcrumed upon said supporting frame, arodconnecting said foot lever and said clamping frame, a spring tending tonormally hold said clamping frame in an inoperative position, a shearbar fulcrumed at one end on said main frame and with the other endadapted to be moved adjacent one side of said die, a link having one endpivotally connected with said shear bar to one side of the fulcrum, alever fulcrumed on said supporting frame and pivotally connected to theother end of said link, an operating lever fulcrumed on said main frame,and an operative connection between said operating lever and saidfirst-mentioned lever.

In witness whereof, I have hereunto affixed my signature in the presenceof the witnesses herein named.

JAMES VOOD.
